To all whmn it may concern:

Be it known that I, ORLA H. WATKINS, a citizen of the United States, residing at Arnes, in the county of Story and State of Iowa, have invented a new and useful Reversible Hinge for Sofa-Beds, &c., of which the followin is a specification.

y object is to provide a simple, strong, and durable hinge specially adapted to be connected with the ends of two mating parts of a sofa or the like in such a manner that it can be extended flat in the same horizontal plane to serve as a bed or either one of them folded upward and retained in osition as a back for a sofa, while the other 18 flat upon a base to be supported as a seat, as in the so called Davenport sofas.

My invention consists in the arrangement and combination of parts of the hinge relative to each other and a sofabed, &c., as hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure 1 shows the four parts of the hinge pivotally connected and in their normal positions as reqluired for packing and storing advantageous y. Fig. 2 shows how the hinge is applied to the bottom and back of a foldable lounge, bed, or sofa and one of the parts in position to serve as a back and the other as a seat. Fig. 3 shows the positions of the two foldable parts of the article of furniture into which the must be placed before they can be put into tlie same horizontal lane to extend outward from the base equal istances. Fig. 4 shows the back placed flat on the base and the bottom in an elevated position, and dotted lines indicate how the bottom must be adjusted to release it from one of the hinge members before it can be lowered into position, as shown in Fig 5, which shows the seat and the back in the same horizontal plane as required for use as a bed.

The numeral 10 desi ates the ends of a base, referably more is, for the foldable part of a sofa, &c.,fitted to the parallel sides, as shown in Fig. 2, or in any suitable Way, as required for connecting therewith the seat 12 and the back 13, that are pivotally connected by hinges 14 in a common way.

My reversible hinge consists simp y of a fiat plate 15, that may vary in configuration and has a swell or stud 16 referahly integral therewith and on its outside and near the edge of the widest top part, as clearly shown.

It is also provided with several holes. A

rnet al'strap or link 1? is pivoted to the plate 15 near to and above the stud 16. A second link 18 is pivoted tothe plate in parallel position with the link 17, and a third link 19 is pivoted to the plate between the first and second links at the lower end of the plate 15 and provided with a notch, as clearly shown in F1 1. One of the hinges thus construct ed is fixed to each end of the back 13 and the links 17 and 18 pivoted to the end pieces 10 of the base, and the link 19, having a notch a, in its end portion, is detachahly connected with a staple 20, fixed in the end of the seat 12, as required to lock the foldable back and seat in fixed positions, as shown in Fig. 2, by

means of the staple engaging the link by entering the notch in the link.

Fig. 3'shows the positions of the different parts relative to each other and the base, as required, preparatory for reversing the bin es and the positions of the seat 12 and has 13, as shown in Fig. 4, and dotted lines in Fig. 4 indicate how the positions of the seat 12 and the link 19 must be changed in order to release the links 19 from the staples 20 before the seat 12 can be placed flat on the base, as shown in Fig. 5, for utilizing the back and seat as a bed. When the seat 12 is in position as shown in Fig. 4, and the back 13 and link 19 as indicated by the dotted lines, the link 19 will contact with the stud 16, and the stud will by such frictional contact retain the link 19 stationary and allow the notch in the link to esca e from the staple 20, as re uired to unlock seat 12 and to be folds down fiat upon the base.

Having thus set forth the purpose of my invention, its construction, application, and manner of use, the practical operation and utility thereof will be readily understood by persons familiar with the art to which it pertains.

What I claim as new, and desire to secure by Letters Patent, is

1. As an article of manufacture, a flat metal plate having perforations for the passage 0 screws, a stud on its outside near its edge at one end portion, a metal link pivoted near the stud, a second and shorter link ivoted in parallel position with the first ink and the fires ends of said links provided with screw-he is, and a third link pivoted to the plate and'prov'ided with a notch in the edge of its free end portion, for the purposes stated.

2. A reversible hinge consisting of a flat metal plate, having screw-holes and fixed to the end oi the back of link pivoted to the fixed of a seat hinged to the back, a second and shorter link pivoted to the fixed plate in alinenient with the first link and to the end of a seat and a third link provided with a notch in its free end portion pivoted to the lower end and corner portion of the fixed plate and a staple lixed in the end of the seat, as shown and described, for the purposes stated A reversible hinge and locking device for sofa-beds, comprising a flat metal plate a sofa-bed, a metal plate and to the end having a stud on its outside fixed to theend ol' the back of a s0labed, a sofa-seat and back 15 hin ed to ether, said plate lixed to the end of the bac a link har'ing a notch in its edge pivoted to the plate, a staple lixed in the end 01 the seatnfwo links pivoted to the plate and to a base, and a base for supporting the seat and back, arranged and combined to operate as set forth.
